HERMANN A. GISEKE, OF OMAHA, NEBRASKA.

, CHEMICAL FIRE-EXTINGUISHER.

Specification of Letters Patent.

Application filed September 2, 1908.

Patented Dec. 15, 1908.

Serial No. 451,445.

To all whom it may concern:

Be it known that I, HERMANN A. GrsEKE, a citizen of the United States,residing at Omaha, in the county of Douglas and State of Nebraska, haveinvented certain new and useful Improvements in ChemicalFire-Extinguishers; and I do hereby declare the following to be full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification,

This invention relates to new and useful improvements in chemical fireextinguishing apparatus, and the object in view is to produce a simpleand efficient device of this na ture adapted for use upon cars and otherplaces, and so arranged that chemicals con tained in bottles and whenallowed to combine as the bottles are broken, will produce the desiredgas for extinguishing a fire.

More specifically, the invention com rises a receptacle containingfrangible bott es in which the acid and soda are adapted to be held, andin the provision of a chain passing about the bottles and connected to arotatable shaft extending through the end of the receptacle and providedWith a hand wheel and so arranged that when the shaft is rotated, thechains will cause the bottles to break and allow the chemicals to mixand be agitated by means of a stirrer upon the shaft.

The invention comprises various other details of construction andcombinations and arrangements of parts which will be hereinafter fullydescribed and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which z-Figure 1 is a vertical sectional view through the device, and Fig. 2 isa cross sectional view.

Reference now being had to the details o the drawings by letter, Adesignates a tank or receptacle of any size or shape and within whichare contained a pluralit of bottles designated by letters B and C, t eformer of which are ada ted to contain soda and the latter a suitab eacid, which, when combined with the soda, will produce a fireextinguish.- ing gas. Chains I) are fastened at their ends to the innersurface of the wall of the receptacle, and each chain passes about oneor another of the bottles B or C and their inner ends are fastened tothe centrally located rotatable shaft E which passes at its upper endthrough an aperture in the top of the receptacle, `and has a hand wheelE fastened thereto, whereby the shaft may be rotated.

A stirrer F is fastened to the lower portion of the rod E and serves thepurpose of agitating and mixing the chemicals after the bottles havebeen broken. A drain pipe G leads from the lowest portion of thereceptacle A, whereby the contents of the receptacle may be drawn 0H,and a screw cap I-I is fitted in an aperture in the lower ortion of thereceptacle and affords means W ereby access may be had to the lowerportion of the receptacle. Screw caps I are fitted in openings in thetop of the receptacle and through which openings access may be had forfilling the receptacle.

A pipe J leads through the wall of the receptacle and its inner endopens near the bottom of the latter and is provided with a valve N. Ahose pipe O is shown as connected to said pipe J and affords meanswhereby the mixture of the gas may be conveyed at any suitable locationfor the purpose of directing the same upon a fire to be extinguished.

The operation of my invention is as follows. The parts being assembledas shown and described, when it is desiredto operate the a paratus, aperson, by turning the hand wheei may cause the inner ends of the chainsto wind about the shaft E, and each chain passing about a bottle, willbe constricted, causing the bottles to break and the contents thereof tocommingle. rotary movement of the shaft in one direction or the othermay cause the stirrer to thoroughly agitate the chemicals, and the gas,as it is generated, may be conducted through the pipes and upon the fireto be extinguished.

What I claim to be new is l. Ay chemical fireextinguisher comprising areceptacle, frangible bottles mounted therein and adapted to containchemicals, chains passing about the bottles and fixed to the receptacle,and a rotatable shaft mounted within the latter and about which saidchains are adapted to wind, asset forth.

2. A fire extinguishing apparatus comprising a receptacle, chainsfastened at their outer ends to the inner surface of the wall of Afurther naled in the upper end of the receptacle and about which saidchains are adapted to wind7 each chain adapted to surround a bottle7 asset forth.

3. A fire extinguishing apparatus comprising a receptacle, chainsfastened at their outer ends to the inner surface of the wall of thereceptacle, a rotatable shaft journaled in the upper end of thereceptacle and about which said chains are adapted to wind, each chainadapted to surround a bottle7 and a stirrer movable with said shaft7 asset forth.

4. A iire extinguishing apparatus comprising a receptacle, chainsfastened at their outer ends to the inner surface of the wall of thereceptacle, a rotatable shaft journaled in the upper end of thereceptacle and about which said chains are adapted to wind, each chainadapted to surround a bottle,A said chains adapted to support thebottles by frictional contact therewith, and a stirrer upon said shaft,as set forth.

5. A chemical fire extinguisher comprising a receptacle, chains fastenedto the inner surface of the wall thereof at points diametricallyopposite, chemical containing bottles about which said chains pass, arotatable shaft journaled in the top of the receptacle and about whichthe inner ends of the chains are adapted to wind7 a stirrer fixed to theinner end of said shaft, and a pipe leading from the receptacle, as setforth.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.

HERMANN A. GISEKE.
